Does anyone know what the current state of this header is? Looking back
at the list archive it looks like it might have been used in loop
prevention at some point, but looking at the code, I can’t see any
evidence of that now (3.6.1-3.6.6).
Obviously this leads to the question, can I safely remove the setting of
the header from my local SendEmail.pm without trashing Loop Prevention
or anything else?
